Adding Hackintosh to PC using new disk

Good day, I'm using PC Tower with the following:

• MOBO: AsRock Z170 Professional Gaming i7
• GPU: Nvidia GTX970
• RAM: 16GB
• HDD: 1TB Hard-drive
• SSD: 240GB Kingstone SSD Drive

Now, I've tried installing Hackintosh on my laptop a while ago, of course returned no success, but I always liked the look and usage of MacOS, so I was thinking, If I add another HDD or SSD disk to my computer(thinking about 200GB, no more), and install MacOS on that disk, then I should be able to launch to Win10 through my main SSD disk and to MacOS using that new disk I Would buy.

Now my questions are following:

• Which would be better? SSD or HDD disk?
• Is it even possible to work that way? Using several HDDs or SSDs?(my logic says yes but i'm asking because i might be wrong)
• If I change those settings in BIOS, which Hackintosh requires, how much will that change performance of Win10? Or does it work without changing them too?
• Questions also will be added in Comments when I find more of them...

I already checked Hackintosh build for my specific MOBO and see success and only thing left are these questions I need cleared and any suggestions from professionals. :D

Thanks!
